LOAD-RETAINING MEANS FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 706,797, dated August 12, 1902.

Application filed March 26, 1902. Serial No. 100,098. (No model.)

Minnesota, have invented certain new and useful Improvements in Load Retaining Means for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to load retaining means for vehicles, and especially to stakegoverning means for loggin g or platform cars, and has for its object the provision of a pivotally-supported stake-socket and simple, durable, and efficient means for controlling the position thereof.

It consists, in combination with a suitable car or vehicle, of a socket secured thereto, a stake-socket or stake pivotally secured therein, a pivotal lever for securing said socket in a vertical position, a latch for securing said lever against movement, and means to operate said latch.

It also consists of certain other constructions, combinations, and arrangements of parts, as will be hereinafter more particularly described and claimed.

In the drawings, Figure 1 is a side elevation of a portion of a car, showing my said invention. through one of the bolsters of said car, showing my invention, partly in section, secured thereto. Fig. 3 is a detail of the latch-operating wedge forming part of my said invention.

In the drawings, A is a bracket vertically 5o trically pivoted, as at 0 within the cleft of said bracket A and near the upper face there- Fig. 2 is a transverse section of. The shank of the lever C extends down* wardly and is provided near its lower end with a laterally-extending wrist-pin c or equivalent, which is at all times engaged by a latch D. Said latch D is pivotally secured at one end within the cleft of said socket B, and is formed intermediate of its ends with a segmental slot, as at d, with an upwardlyextending notch, as at d which slot and notch are adapted to engage the wrist-pin a which in operative position is engaged by said notch and when disengaged therefrom travels along said slot. To operate said latch, I provide the combined locking -bolt and lifting-wedge E, formed with an angular extension c, adapted in operative position to overreach the free end (Z of said latch D, and further formed with an upwardly-inclined or wedge portion 6 adapted in the operation of disengaging said latch D to raise the same sufliciently to free said pin 0 from said notch d Said bolt E is further formed with a vertical extension or stop 6 adapted to prevent the withdrawal of the end of said bolt from beneath said latch when said latch is raised.

To one end of the bolt E, I secure the draw* rod c extending to the end of the car and provided with an angular or other suitable handle e and with a notch 6 adapted to engage a pin e in the body of the car to secure said rod 6 against longitudinal movement; but said rod and its terminal form and fass 'tening e 6, and 9' may be of any suitable or desirable construction. At the opposite end of said bolt E, as at e I preferably secure a connecting draw-rod a, secured at its opposite end to a similar bolt to operate other and similar stake-controlling means, so that a described a stake-socket such as I prefer to use, it is obvious that an integral stake supported in like manner would also lpe within the scope of my said invention.

In operation the socket D is raised to vertical position by hand or otherwise, the lever O being meantime held in receptive position by the latch D, maintained in elevated position by the inclined portion 6 of the partlywithdrawn bolt E. As soon as the finger b is in position to be engaged by the finger or jaw c the bolt E is shot forward by means of rod when the latch D drops of itsown weight, and the foot of the leveralso drops in an are by gravitation, causing the finger c to engage the finger b, the notched portion 01 of said latch dropping over the pin 0 of said lever and securely locking the same.

The bolt E continuing its forward movement, the angular portion e thereof overreaches the free end of latch D and secures the same inposition, and the bolt E is then secured against movement by any suitable fastening, as aforesaid, at the handle end of the rod 6 When the bolt E is withdrawn to disembark the load, the angular portion 6 first clears the latch D, which is then lifted by the inclined or Wedge portion e of said bolt, causing the pin 0 to disengage from the notchd and subsequently to follow slot (1. The lat-. eral strain of the load now forces the top of said socket away from the car, the finger b, pulling on the finger c, causing a pivotal movement of said lever C until the fingers b and c are disengaged, whereupon the socket B and contained stake fall radially downward, pivoting on bolt A and the load is released.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-

- 1. In a load-retaining apparatus, the combination with a suitable load-bearing structure, of a bracket extending therefrom, a stake-carrying socket pivotally supported in said bracket, a lever for locking said socket in a vertical position, means carried by said socket engaging said lever for effecting the locking operation, and means extending beyond said socket for operating and controlling said lever, substantially as described.

2.
